Proprietary Cool Wax Blend is made of the highest-quality, food-grade paraffin wax. Safety Wicks All our wicks feature a “safety collar” so when the candles burn down, it will self-extinguish to prevent broken glass and spilled wax. Long Lasting We’ve quality tested each VoLight to ensure a consistent burn of 15 to 30 hours. Mix and Match different scents to create a unique fragrance experience.
